Multiple Select

Select all the correct statements about filament and staple yarns.

• Filament yarns are made from long continuous fibers.

• Staple yarns are made from short fibers twisted together.

• Filament yarns are always natural fibers.

• Staple yarns are always synthetic fibers.

Multiple Choice

What is the main purpose of pressing fibers into bales?

• To make them easier to transport to yarn manufacturers

• To improve the quality of the fibers

• To dye the fibers before spinning

• To remove impurities from the fibers

Multiple Select

Which of the following are functions of the carding process?

• Separating tangled fibers into individual fibers

• Aligning fibers so they are parallel

• Removing large trash like sticks and metal

• Forming a flat web or sliver

Fill in the Blanks

The optional process that further aligns fibers and removes the shortest fibers is called

.

Multiple Choice

What is the main purpose of the drawing process in yarn manufacturing?

• To combine several slivers and create a strand with even thickness and weight

• To dye the fibers before spinning

• To twist the fibers into yarn

• To remove all impurities from the fibers

Multiple Choice

What is the main purpose of the spinning process in yarn production?

• To dye the yarn

• To pull roving to the desired thickness and tightly twist it into yarn

• To clean the fibers

• To blend different fibers together

A yarn label reads: 58% Cotton, 39% Polyester, 3% Elastane. This is an example of a

yarn.

Multiple Choice

Which of the following statements about blends is correct?

• Blends are made from a single type of fiber.

• Blends are always more expensive than single-fiber yarns.

• Blends combine fibers to enhance good characteristics and reduce less desirable ones.

• Blends cannot be used in clothing.

Fill in the Blanks

Manufactured fibers left as filaments are spun directly into yarn through a

yarn process.

Multiple Choice

Which device is used to push melted polymer through tiny holes to form synthetic filaments in the filament yarn process?

• Spinneret

• Pump

• Bobbin

• Heated drum rolls

Multiple Choice

What is the main difference between staple fibers and filament fibers?

• Staple fibers are long and continuous, while filament fibers are short and small.

• Staple fibers are used only for making ropes, while filament fibers are used for fabrics.

• Staple fibers are small, short lengths of fiber, while filament fibers are long, continuous strands.

• Staple fibers are synthetic, while filament fibers are always natural.
